PTR is;

Barbarian; Raekor's
Crusader; Akkhan
Demon Hunter; Marauder
Monk; Inna's
Witch Doctor; Zunimassa
Wizard; Delsere's Magnum Opus

I didn't really like Akkhan's, although its potential to just do AoE damage is much better than Invokers, but Invokers just got a further +150% damage IIRC in the PTR. Magnum Opus took a hit with Twisted Sword capping out at 5 Twisters also IIRC. I've not really done a Pet Build, and although I may just play a Crusader (possibly as a Hardcore Cherry Popper, so that I can try and get the Hardcore Avarice with ease, because I know how to play, and gear - ish - mostly thanks to you guys - without being overly fragile). I've not really played a Witch Doctor, or a pet build, although I may even try for a machine gun general Crusader also.
